My iMac early 2008 started to boot to a white screen.  Replaced the logic board, no change. Removed the graphic card, gently set it up in a vice and applied hot blown air with a paint gun for about 3 minutes to reseal any broken solder joints.  Let it cool and reinstalled with new thermal paste.  Problem cured.
